SPECIFICATION forming part of Letters Patent No. 729,596, dated June 2, 1903. Application led January 5, 1903. Serial'No.137,758. (No model.)

fo all whom. it may concern:

Be it known that I, MARTIN JOHNSRUD, a citizen of the United States; residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in echanism for Operating Oream-Separator Oy inders, of which the fol-' lowing is a specification.

This invention relates to improvements inV and arrangement of the various parts there-A of, all of which will be hereinafter fully described, aud pointed out in the appended claims.

Experience'and practice in the art to which my invention pertains have shown that in order to attain the best results the separatorcylinders should be made quite long and narrow, and heretofore they have been made and provided with a shaft extending from their lower ends to engage the operating mechanism. As the cylinders are quite long, it is apparent that a slight springing or deviation of said shaft from an axial line through the cylinder will throw it out of alinement or plumb, thus causing a great deal of friction in the rotation of the cylinder or rendering the mechanism inoperative.

It is therefore the principal object of my invention to provide a mechanism for supporting and operating cream-separatorcylin-4 ders which shall be so constructed as to have bearings foiboth ends of the cylinder and so made that the shaft ordinarily used on the lower end of the cylinder may bedispensed with, thereby affording a smooth and accurately running mechanism in which there are 11o parts tobesprung orto get out of order. Another object of the invention is to so construct the device that the cylinder may easily be placed in position and securely retained, yet readily removed whendesired'.

A further object is to so construct the bear-n ings lfor the ends of the cylinder as top revent vibration, thus causing it to run perfectly smooth.

5o Other objects and advantages of the inven- Ation will be `disclosed in the subjoined description and explanation.

Referring to the accompanying drawings, Figure 1 represents a front view in elevation "of" aniapparatus embodying my invention, showing the separatorcylinder removed. Fig. 2 is a View, partly in section and partly Tin elevation, taken on line 2 2 of Fig. l, looking in thedirection` indicated by the arrows, but showing the separator-cylinder and its cap in position. Fig. 3 is a perspective view of the upper portion of the device, showing by dotted lines the positions the parts will assume when the cylinder is in place and by continuous lines the positions they will assume when it is desired to remove the cylinder. Fig. 4 is a view in elevation of a portion of the main frame, showing the construction of the portion thereof to which the releasing-lever is fulorumed. Fig. 5 is a plan view of the main frame, showinga portion of the releasing-lever. Fig. 6 is a sectional plan view of the upper bearingor journal-box for the cylinder. Fig; 7 is a sectional view thereof, taken on line 7 7 of Fig. 6, looking in the direction indicated by the arrows. Fig. 8 is a sectional view of the lower bearing orjournal-box. Fig. 9 is a sectional view of the lower part of the upper portion of the wormshaft. Fig. l0 is a similar'view of a portion of the main frame,shovvingu the spring-actu- 'ated press-button; and Fig, ll is a view of a portion of one of the supporting-rods for the upper journal-box.

Similar letters refeij to' like part-s throughout the dierent views of t-he 'drawings.

The main frame consists of a base portion A and an upright tubular portion A', having an enlargement A2, on which the supportingrods for the upper bearing or journal-box are mounted. The base 'portion of the main frame is formed with a hollow extension a., which may be closed by a curved and detachable door a', as is clearly shown in Fig. 2 of the drawings.

Transversely journaled in the-sides ofA the extension a of the base is a shaft B, on which -is mounted between said sides a gear C, which meshes with a worm D on the worm-shaft D',

which is vertically journaled in the base por- IOO tion of the frame and extends upwardly therethrough.

Mounted on the shaft B near one of its ends is a pinion B, with which the main or driving gear C meshes, which gear is mounted on one end of the shaft c, horizontally journaled on the tubular portion A of the main frame, near the lower end of the enlargement A2 thereof. On the opposite end of the shaft c from that on which the gear C is mounted is secured a crank C2, used for operating the device. Instead of using a crank on said shaft it is apprrent that a pulley may be substituted therefor, to which a belt may be applied for transmitting power.

The lower portion of the enlargement A2 is provided with a segmental recess a2 for the reception and operation of a segmental lug e on the inner surface of the releasing-lever E, which is fulcrnmed on the lower portion of the enlargement A2 by means of a screw or bolt e', located in an opening e2 therefor in the lower portion of said enlargement. Near the recess a2 the enlargement A2 is provided with an opening e3 for the reception and operation of a push-button E, which is pressed outwardly by means of a spring c4, located in the opening e2 between its inner end and the inner end of said button, vwhich is used to lock the releasing-lever E and the rod F, which it lifts, in their lowered position, as shown in Fig. 2 of the drawings. For this purpose the lever E is provided with a recess e5, with which the button E' will engage when projected. The rod Fis vertically and'loosely located in an opening l) in the enlargement A2, which opening communicates with the slot or recess A2, so that the segmental lug e of the lever E may engage the lower portion of the rod F, which is preferably provided near its lower end with a recessffor the reception and operation of said lug.

Secured to the enlargement A2 and extending upwardly therefrom in parallelism with the rod F is another rod F', which rods project a slight distance above the top of the main frame, as is shown.

The upper bearing or journal-box for the upper end of the separator-cylinder G comprises a piece or casing G, usually circular in form and having a central circularopening g forthe ring or cone G2, which is provided on its inner surface with a circumferential groove g to retain oil or a lubricant. The lower portion of the casing G/ is formed with an inwardly-extending annular flange g2, in which is located a ring g2, having a flange g4 to overlap the bottom of the casing, and which ring is held in place by screws g5, secured in the casing. Between the flange g2 and the ring g2 are located a number of springs gs, which extend upwardly and impinge the outer surface of the cone, which dts loosely in the casing, thus affording a yielding or cushioned bearing for the upper end of the cylinder.

As shown, the cone is held in position by means of a plate Q7, fastened to the casing by screws or otherwise, and is provided with one or more pieces of wick or fibrous material gs in its walls to distribute the oil from the groove g therefor. The casing G' is provided with two arms or extensions h and h', each having near its free end an opening h2 to receive the upper ends of the rods F and F.

One of said arms is secured to the rod F by means of a screw h3, so that it as well as the casing will move with said rod.

The lower bearing, in which the worm-shaft D is journaled, consists of a casing I, circular in form and provided with a central opening i, in which is loosely located a cone L, which has on its inner surface a circumferential groove m to retain oil. The cone L is held in-position by means of a plate m, secured to the casing by means of screws or otherwise. Located between the lower portion of the casing I and an annular flange n on a plate N, secured ,to the bottom of the casing, are a number of springs o, which press against the outer surface of the cone L, so as to form a yielding or cushioned bearing for the worm-shaft. The lower bearing or journal-box, now under consideration, is located in the upper part of the base portion of the main frame, as is clearly shown in Fig. 2 of the drawings. The upper portion of the cylinder G is contracted to form a neck d, which fits in the openings of the cone G2, so as to rotate therein, and the lower portion of the cylinder is provided with a vertical socket or opening d to receive the upper end of the worm-shaft D', which shaft is provided near its upper end with a transverse pin or projection d2 to engage the depending pins d2 on the lower end ofthe cylinder. Located on the upper end of the main frame and surrounding the upper portion of the cylinder is a cap M, which is provided with spoutsp and p for the discharge of cream and milk, respectivelyA From the foregoing and by reference to the drawings it will be seen and clearly understood that by pressing the button E inwardly the lever E may be raised to the position indicated by continuous lines in Fig. 3 of the drawings, in which operation the rod F will be lifted by reason of the engagement therewith of the segmental lug e on the lever. When thus lifted, one of the arms of the upper journal-box will be disengaged from the rod F', thus allowing it to be turned to the position shown by continuous lines in Fig. 3, when the cylinder may be inserted into the tubular portion A of the main frame, so as to rest'on the upper end of the worm-shaft and so that the rods d2 will engage the pin d2 on said shaft. When thus placed in position, the cap M may be placed over the upper end of the cylinder, so as to rest on the top of the main frame,and the upper journal-box turned to the position shown by dotted lines in Fig.

3, when one of its arms will engage the rod F, at which time the said journal-box may be lowered by lowering the lever E and rod F, when the push-button E will engage the recess e5 in the lever and lock the parts in position. When the parts are thus arranged, power may be applied to the shaft c, when the cylinder will be operated with great speed and accuracy.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination with the main frame, of a worm-shaft vertically journaled in its lower portion and having means to engage the lower portion of the cylinder, a journalbox vertically and rotatably movable on the upper portion ofthe main frame, a separatorcylinder located in the main frame and having means to engage the worm-shaft and upper journal-box, and means to operate said shaft and to raise and lower the journal-box for the upper end of the cylinder, substantially as described.
